Layer intersection group - ArchiCAD Layer

[andrewzarb]

I have found that my ArchiCAD Layer has its intersection group set to two in some layer combinations and one in others.

I can't change the layer intersection group of the ArchiCAD Layer in the Layer settings or the Attribute manager.

Two questions:

1.How did it change?

2.How do I change it back?

Thanks for the replies,

This issue raised mainly out of curiosity, after it caused one user in my office some (needless) consternation.

I do not advocate the use of the ArchiCAD layer for anything that is not temporary either.

My original questions were:
1.How did it change?
2.How do I change it back?

It appears that it's not a feature in this case, it's a bug.
